Transport Fever 3 Map Seeds: How to Recreate and Share a Map

A Transport Fever 3 map seed is one input to the game's procedural terrain generator. It is useful when you want to revisit a landscape or share it with another player, but a seed string on its own is a poor description of a map. Save the climate and generation settings alongside it.

What does a map seed affect?

The official Transport Fever 3 modding wiki documents a "Seed" input in the terrain generator's map data. The generator uses a node graph to build biome regions, heightmaps, forests, and other assets. The developer's environment blog explains that players can adjust the balance of biomes while creating a map, and that a different random distribution can produce a very different layout even when the initial settings look similar.

That means a screenshot or a seed copied without its settings may be hard to reproduce. Treat the seed and the rest of the map setup as a package. The official sources above explain the generation system; they do not publish a ranked list of "best" seed strings.

What to record when sharing a seed

Before starting your game, write down or screenshot:

1. The exact seed as displayed in your map setup.
2. The climate: Temperate, Tropical, Dry, or Subarctic.
3. Map size and shape.
4. Terrain and biome choices, such as water, mountains, or swamps, when you changed them.
5. Town and industry density, difficulty, and any enabled mods or custom generator.
6. The game version if you want someone to reproduce the map later.

The last points are practical reproducibility advice. They are not a claim that every one of these settings changes the same terrain node. If another player's map differs, compare the full setup first.

Choosing a climate for the map you want

These are map-selection considerations, not guaranteed outcomes for any particular seed. The environment overview and developer blog describe the available landscapes in more detail.

A real example, with a limitation

In a Subarctic Very Hard playthrough, a player selects low town and industry density, shows the map setup, and says the seed is in the video description. The collected transcript does not contain the seed string, so this article cannot verify or republish it. The example is still useful for seeing why density and climate belong next to any shared seed: they shape the challenge the player is trying to recreate.

If you find a community seed, check that it explicitly says Transport Fever 3. Search results for this topic also contain seeds and instructions for Transport Fever and Transport Fever 2.

Seed versus Terrain Generator Editor

You do not need to edit game scripts to use a normal map seed. The separate Terrain Generator Editor is a modding tool inside the Map Editor. Its documented settings include a custom seed for previews, and the wiki says it requires enabling experimentalTerrainGeneratorEditor in settings.lua. That workflow is for changing generator logic, not a required step for starting an ordinary seeded game.

Quick answer

For a shareable Transport Fever 3 map, keep the exact seed plus the full setup. Choose a climate that suits your routes, preview the terrain before committing to a long game, and avoid relying on unverified seed lists copied from earlier games.
